Connecting to Planet Fitness public WIFI

I am unable to connect my 2 week old iPhone 5c or my first generation iPad to the public wifi at my gym. I have tried all,the suggested resets and troubleshooting tips to no avail. The odd thing is that an employee there has the exact phone I have, but can connect just fine. Here are a few things that I have noticed on both the iPhone and iPad in this situation:

Planet fitness wifi shows up as an available network, but when I try to join it just spins and spins and never connects with the check mark.

When the wifi first shows up, there is no IP address listed. After some time, there will be an ip address, but it will be totally different than the ip address on the employees iPhone that is successfully connected.

I went into "static" and entered all the identical information with ip address, domain,etc to the employees phone. When I did that, it seemed to connect, however I was not receiving any signals even though the wifi icon was present on the phone and the planet fitness wifi was checked.

Only 1 week ago, the phone connected fine without problems. However the last 2 days in a row, both my iPad1 and iPhone 5c are having the same problem. They have rebooted their wifi system several times and that didn't help either.

I am guessing the differing ip addresses may be to blame, but why is it that an identical phone can connect, but not mine?

Advice is appreciated!
